To all whom it may concern:

Be it known `that I, STEPHEN I. ARM- BRUSTER, a citizen of the UnitedStates, residing at Plymouth, in the county of Richland and State ofOhio, have invented a new and useful TNire-VVorking Machine, of whichthe following is a specification.

The present invention relates to means for operating on wires, and moreparticularly for roducing terminal loops thereon.

he principal object of the invention is to provide a comparativelysimple, thoroughly practicable, and highly eiiicient machine, which willhave a large output, and will form loops in either or both ends of awire, said machine being readily adjustable to wires of diiferentlengths and various diameters.

The machine is Iparticularly adapted for producing termina loops on ianowires, wires for brick machines, ties or hay and other bales, and infact for any looped wire.

An embodiment of theinvention that is at present considered thepreferable one is illustrated in the accompanying drawings, but it willbe evident from an inspection of the claims hereto appended, that theinvention is not limited solely to the lparticular constructiondisclosed.

In the drawings: Figure 1 is a top plan view of the machine, the centralportion being broken away. Fig. 2 is a side elevation of the same. Fig.3 is a vertical longitudinal sectional view on an enlarged scale throughone of the wire looping and twisting mechanisms. Fig. 4 is a crosssectional view through the same. Fig. 5 is also a cross sectional viewon the line 5 5 of Fig. 3. Fig. 6 is a detail view illustrating themeans for controlling the longitudinal movement of the twistingmechanism. Fig. 7 is a detail sectional view on the line 7-7 of Fig.` 1.Fig. 8 is a detail sectional view showing the locking means for thetwisting mechanism. Fig. 9 is a detail view of the idler. and theactuating means for the loclr of the twisting mechanism. Fig. 1() is adetail sectional view illustrating the structure of one of the feedingdevices. Fig. 11 is a detail sectional view on the line 1111 of Fig. 10.Fig. 12 is also a sectional view illustrating the operation of the wireholding clamp when in a position to receive a wire. Fig. 13 is a detailperspective view of the clamp with the jaws isassociated. Fig. 14 is adetail sectional view of the clamping mechanism that is associated withone of the wire looping and twisting devices. Fig. 15 is a detailsectional view through one of said looping and twisting devices. Fig. 16is a view showing a wire vas produced by the machine.

Similar reference numerals designate corresponding parts in all thefigures of the drawm s.

In the embodiment disclosed, a supporting frame is employed, whichincludes spaced tracks or bars 17 bridged by suitable cross pieces 18and supported in any suitable manner.

Two wire looping and twisting mechanisms are mounted on the end portionsof the frame, and are designated generally by the reference numeral 19.As these mechanisms are duplicates, but one will be described in detail.Their inner ends are spaced apart, as clearly shown in Figs. 1 and 2,and the wires to be operated upon are held between them. The holdingmeans is in the form of sets of clamps mounted on the central crosspieces 1S, and as shown in Figs. 4 and 14, said cross pieces haveupstanding stationary clampimg jaws 20. Coacting with one side of eachaw is a swinging jaw 21 pivoted, as shown at 22 in an opening 23 in thecross piece and having a depending arm 24. This arm rides against theeccentric edge of a rotatable cam 25 secured to a shaft 26 that isjournaled in a supporting bracket 27 mounted on the frame. The shaft 26has a gear wheel 28 secured to its outer end, and in mesh with a pinion29 fast upon a tubular shaft 3() that is mounted on a shaft 31connecting the two wire looping and twisting mechanisms, as hereinafterset forth. The tubular Shaft 8() has a gear connection 32 with a maindriving shaft 33 journaled in another suppoijting bracket 34 that ismounted on the frame. It will thus be evident that upon the rotationofthe shaft 26 and cam 25, the arm will be swung so that the jaw 21 willbe moved toward and from the stationary aw 20, the bearing of said armagainst the cam 1seing maintained by a spring 34a,

hown in Fig. 4. The clamps thus described are adapted to receive andhold the wires during the looping and twisting operations, one of saidw' Yes being shown in position in Fig. 1, and designated 35.

For the purpose of feeding the wires, the following mechanism ispreferably employed. A trough. 36 is mounted on suitable arms 37 at oneside of the machine, and the wires hav-i ing first been out the desiredlength, are successively fed to the trough by any suitable means (notshown). Mounted on each set of brackets 27 and 34 at one side of themachine, is a shaft 38 that has a gear connection 39 with an idler 46journaled on the looping and twisting mechanism, as hereinafterdescribed, this idler 46 being in mesh with the gear 28 of the shaft 26,and consequently being continuously rotated. Each of the shafts 3Scarries at its inner end an arm 4l, and these arms, as shown in Figs. land 2, are spaced apart. The free ends of the arms operate beyond` theends ofthe trough, and outside the clamps above described. They carry attheir free ends wire engaging and transferring clamps, each of whichconsists of relatively swinging aws 42 and`43 normally pressed togetherby aspring 44 located between projecting tails 45. The clamps are alwaysmaintained in vertical pesitions regardless of the rotation of the armscarrying them, and to this end, one of the jaws 43 of each clamp has ahub 46 'ixed to a spindle 47 that has a beveled gear wheel 4S in meshwith another gear wheel 49 carried by a shaft 50 that is journaledlongitudinally ef the arm 41 in ears 51 projecting from one side of saidarm, as shown in Figs. 4 and 16.

j The shaft 33, which carries the arm 4l, as

illustrated in said Fig. 16, is tubular, and is journaled on astationary axle This axle carries at its inner end a stationary gearWheel 53 that is in mesh with another gear carried by the inner end ofthe shaft 50. The result is that during the rotation of the shaft 41,the gear 54 will be revolved by its engagement with the stationary gear53. Consequently the gears 49 and 4S will be rotated, and because ofthis arrangement, the clamp carried by the arm will always remain invertical position. This will be evident by a comparison of Figs. 11 andl2. As already stated, one of the jaws 43 is thus geared, the other jaw42 swings and therefore has an ear 55 ournaled on the hub 46. This awfurthermore has oppositely extending fingers 56, one of which extendsthrough a slot 57 in the aw 43, and these fingers are located in thebifurcation 58 in the end of the arm in which the clamp is placed. A lug59 or projection formed upon the arm and located in the bifurcation inthe path of movement of the ends of the lingers 56, is thus arranged tostrike said fingers, and as a consequence, the j aw 43 will be swung toopen position twice on every revolution of the arm. The arrangement issuch that as the arm swings ujiwardly past the end of the wire holdingtrough 36, one of the fingers will be engaged by the projection, and asit rides over the same, the jaw v42 will be forced open against theaction of the spring 44, and consequently the jaws are passed onopposite sides of the ends of the wire placed in the trough. After suchpassage, the finger 56 having passed the projection 59, the spring 44can react to close the jaws and therefore the wire will be clampedbetween the same. The two arms and their clamps rotating simultaneimsly,will thus engage the ends of the wire and carry said wire from thetrough tothe clamps, as described. As the free ends of the arms passdownwardly, the opposite lingers 56 will strike the upper sides of theprojections 59. Therefore the jaws 42 will again be swung to openposition just as the wire 35 is deposited in the clamps :2()-`l1, and asthe aws thus release the wire, the jaws 2l are clamped thereupon andsecure said wire in position to be operated upon by the looping andtwisting mechanisms.

As already stated, the looping and twistingmechanisms are duplicates, sothat a description of one is believed to be sullicient for both.Referring now particularly to Fig. 3, it will be observed that a twisterhead 60 is employed that is located in a shell 6l, said shell beingjournaled in the bracket 27 and having an inwardly extending sleeve 62journaled in the bracket 34. The sleeve includes a stein 63 secured tothe head 60. On the shell is loosely journaled the idler 46, alreadydescribed. The head 6() carries an outstanding supporting plate 64, andjournaled thereon, is a looping device, in the form of a pinion 65,shown in detail in Fig. l 5. This pinion is journaled on a centralremovable stud bolt or pin 66 having` a head 67 projecting beyond thepinion, and said pinion also has a bending pin 68 secured thereto andspaced from the stud 67. A gear wheel 69 is in mesh with the pinion 65,and a reciprocatory rack 70, slidably mounted in the head 60 and shell6l, meshes with the gear wheel 69. A. grooved collar 71 slidably mountedon the sleeve 62, secured to the rack 76, and has an annular groove 72in which is engaged one end of a cross pin 73 carried by the upper endof a swinging arm 74, said arm having its lower end pivoted, as shown at75 in the bracket. rThe other end f the cross pin, as shown in Figs. land 7 is engaged in a cam groove 76 formed in the periphery of a wheel77 that is mounted on a shaft 7S. This shaft as shown in Fig. l, isjournaled on the opposite side of the frame to the shaft 38, and isdriven from the idler 4() by a gear wheel 79 fixed to the shaft 78, andin mesh with said idler. lt will thus be evident that during everyrotation of the shal't 78, the arm 74 will be swung back and forth once,thus causing the gear wheel 69 to partially rotate and effecting a halfrotation of the pinion 65. The normal position of the pinion isillustrated in Fig. l, and it ill therefore be evident that when a wire35 is deposited in the clamps, the terminal portion of this wire will belocated between the stud 67 and the pin 68. Therefore when the pinion 65is rotated, the terminal portion of -quently into and out Vof the pathof movement ofthe terminal of the wire. The free end of this jaw 80 isconnected to an arm 82, the lower end of which has a roller 83 operatingin a cam groove 811 in the Wheel or eccentric 25. The cam groove 84 isso arranged with respect to the other mechanism that after the loopingmechanism takes place and the terminal of the wire has been bent againstthe side of the stationary jaw 20, the jaw 80 will be raised, asindicated in dotted lines in Fig. 14, and said terminal will be clamped,the looping operation being thursA completed.

As already described, the head and supporting ear or plate 64 forthelooping device is rotatable, and by this means, the twisting operationis secured. During the looping operation, however, the said head isstationary, and in order to effectively prevent its rotation, a loch isemployed in the form of a reciprocatory bolt 85, which. is slidablymounted in the bracket 27, as shown in Figs. 3 and 8, and engages in anopening j in a socket 86 formed` in the saell 61. A spring 87 bearsagainst the bolt, and normally urges it into said socket. The bolt,however, hasan outstanding pin 88, and this pin projects into the pathof mcvemen-u of a cam track 89 secured to one side ofthe idler 40, asshown in Figs. 3 and 9. Consequently upon every rotation of the idler40, the pin will be withdrawn so as to permit the rota tion of the headand shell to permit the twisting operation. rlhe means for effectingthis twisting operation is preferably con structed in. the followingmanner. A clutch member 90 is loosely journaled on the sleeve 62, andhas a pinion 9i in mesh with a gear wheel 92 fixed to the main drivingshaft 88. Consequently the clutch member 90 is always in rotation, andoperates independently of the sleeve G2; A member 98 is feathered onthesleeve 62, as shown at 94, and is movable into and out of coactionwith the clutch member 90. W hen kout of coaction, the sleeve 62 and thevarious parts carried thereby, is of course stationary, but if saidclutch member 93 is moved into coaction with the clutch member 90, thenthe sleeve 62 and associated parts are necessaf rily rotated. Theseclutch members, preferably have beveled friction. faces, as shown, butthey are also provided withpositive en- 20 to hold the end of the wirecoperating clutch l twisting mechanisms gagin devices in the form ofprojecting pins 95.l n order to secure the automatic operation of theclutch, a swinging arm 96 is employed pivoted at its lower end, as shownat 97. The upper end of this arm, as illus* trated in Figs. l and 5 hascross pin 98, one end of which is engaged in an annular groove 99 in theclutch member 93, the other end coperating with the cam edges 100 of thewheel 7 7 and the adjacent wheel 101 carried by the shaft 78, on whichsaid wheel 77 is mounted. Therefore upon each rotation of the shaft 78,the arm 96 will be swung carrying the clutch member 93 into coactionwith the clutch member 90, vand causing the rotation of the head 60 andassociated mechanism, thus twisting the sides of the wire loop together.ln order to compensate for the shortening of the loop due to thistwisting action, the head 60 and stem 63 have a movement longitudinallyof their axis of rotation, and this movement is controlled by a wheel102 which bears against a head 103 formed upon the outer projecting endof the stem 63, the wheel having a cam portion 104, which permits theinward longitudinal movement' of the stem 63.

After the loops and twists have been made, the wires are in condition tobe removed from the machine. Therefore the following devices areemployed. The shafts 78project toward each other, but are entirelyindependent, Yas shown in Fig. 1. rlhey have fixed to their inner endsarms 105 provided with terminal hooks 1 06, and as these arms swingupwardly, they engage the wires just as the clamping rjaws 21 and 80open. The shafts 78 are furthermore provided with other arms 106a havingterminal heads 1071 that engage the loops .and serve to detach them fromthe looping an d twistiig mechanisms. ll`herefore the wires beingdetached by said heads 107, the arms 105 carry the completed articlesaway from the machine and deposit them on the opposite side to thefeeding mechanism.

As already described, the looping and are duplicates, but are entirelyindependent of each other save for the connecting shaft 31. This shaftat one end ofthe machine is geared, as shown at 1071 to one of thedriving shafts 33 and this driving shaft is provided with a drivingpulley 108 by means of which power is transmitted to the machine. Theother end. of theV shaft is geared as shown in Fig. 2 at 109 to thecorresponding driving shaft, and thus power is transmitted to tltecorresponding mechanism. lt will be observed that the looping andtwisting devices are located in opposition to each other, and in orderthat the machine may be operated on wires of diilierent lengths, one setof mech anis-ms is adjustable toward and from the other.
